Truck Driver Health Requirements – How to Pass the DOT Physical Exam

Before obtaining a CDL, truck drivers must meet all the basic federal and state requirements. One of the requirements is passing a Department of Transportation (DOT) physical. The DOT physical is a health exam mandated by the Federal Motor Carrier Safety Administration (FMCSA) for all commercial motor vehicle operators. A DOT physical helps determine if drivers are physically, mentally and emotionally fit to operate a commercial motor vehicle. Before a truck driver takes the DOT physical exam, there are several health requirements they need to be aware of.

A DOT physical is a way to determine a driver’s physical ability to operate a commercial motor vehicle. During the physical, the examiner will check the driver’s current health status and medical history.

Do I Need a DOT Physical

You must pass a DOT physical if you:

  • Operate a motor vehicle for interstate commerce with a gross vehicle weight (GVW), gross vehicle weight rating (GVWR), gross combination weight (GCW), or gross combination weight rating (GCWR)of 10,001 lbs or more.
  • Operate a motor vehicle designed to carry more than 15 passengers.
  • Transport hazardous materials that require you vehicle to be placarded
  • Are paid to operate a motor vehicle designed to carry more than 8 people

How Often is a DOT Physical Required

After obtaining a CDL, drivers must take the DOT physical exam every two years. Drivers may need to take the exam more often if they have a health condition, such as blood pressure, that needs monitoring. Once you pass the DOT physical, the examiner will grant you a certificate. You will then need to turn your certificate into your employer.
